KY Strain Gauge Chains for Determining Strain Gradients

KY strain gauges (SGs) consist of 10 or 15 very small measuring grids that are placed on a common carrier at a constant spacing (equidistant apart) plus one compensation SG. SG chains are especially suitable for determining strain gradients.

With types KY1, KY2, KY3, KY4, KY5, KY6, KY7, KY8 and KY9 we offer you strain gauges (SG) in various geometries and sizes, each available with temperature responses adapted to the following materials:

Ferritic steel (10.8 ppm/K; 6.0 ppm/°F); temperature matching code: 1
Aluminum (23 ppm/K; 12.8 ppm/°F); temperature matching code: 3
Austenitic steel (16 ppm/K, 8.9 ppm/°F); temperature matching code: 5
Silica/composite (0,5 ppm/K; 0.3 ppm/°F); temperature matching code: 6
Titanium and gray cast iron (9 ppm/K; 5.0 ppm/°F); temperature matching code: 7
Plastic (65 ppm/K; 36.1 ppm/°F); temperature matching code: 8
Molybdenum (5.4 ppm/K; 3.0 ppm/°F); temperature matching code: 9

Insert the temperature matching code in place of the placeholder “x” to get the ordering number of the strain gauge you need. Strain gauges marked with a # symbol are only available matched to aluminum, ferritic and austenitic steel.

Strain gauges available in 120, 350, 700 and 1,000 Ohms

Measuring grid consists of constantan, measuring grid carrier is polymide

Simplified Documentation and Parameterization

To optimize the measuring point documentation each strain gauge includes two stickers which can be placed next to the measuring point and near the measuring amplifier. Benefit from the parameter information directly in the measurement setup:

QR code that directly links to the data sheet of the respective strain gauge
The product and production batch numbers
The k-factor and a additional space for your notes
QR code containing the values of the individual strain gauge to simplify computer-aided parameterization or documentation with a scanner

Please note: newly produced strain gauges all come with the sticker in stock, strain gauges still in stock do not have this feature yet.
